Improvement in carpet-cleaners



UNITED STATES PATENT OEEIGEo 'HENRY S. ALLISON,AOF NEV YORK, N. Y.

IMPROVEMENT lN- CARPET-CLEANERS.

Specification forming part of Letters Patent No. 146,975, dated February 3,1874; application tiled August 5, 1873.

the carpet was either made to travel from one reel to another and back again while the beating and brushing took place, or else the ends ofthe carpet were tacked together, and the carpet, thus made endless, was being propelled continuously and horizontally in one direction by feed-rollers, and had to be supported by a bed of cords or other open-work where the blows ofthe beaters were given. Nevertheless the carpet had a chance to bag between the cords or in the open spaces of the supportingbed, and thus vthe bed would receive more of the blows than the carpet.

The object otl my invention is to construct a carpet-beating machine of the endless kind, in which the carpet, while being under the action ot` the beaters, shall travel upward, so as to cause the weight of the carpet below the feedrollers to keep the carpet under tension while the beaters are so treated as to deliver their blows directly below the feed rollers, thus avoiding the necessity of an open bed, which would only destroy the effect of the blows, as shown above. Another object ot' my invention is to construct the beaters themselves in a manner to be more effective.

The machine is constructed as follows: e a are two vertical frames, which support the horizontal cross-beams b, c, d, and e, he feedingrollers f f, which cause the carpet to travel along under the operations of beating and brushing, and the revolving` brushes g g. 'lhe beaters consist cach of two long elastic bars,

h h, fastened with their rear ends to the crossbeam c, and having two or more slats, t' z', fastened to their front ends in a transverse direc tion. The springs are in an inclined direction or position of about forty-tive degrees, more or less, and are being raised each by a rod, 7.-, which is hinged to one ot' the slats t', and slides back and forth upon the upper side ot' the cross-beam e. There is a revolving sha-tt, I, having as many disks l keyed onto it as there are beaters in the machine, each disk havin g two or more pins, m m, in front, by which thcl rods L k are being raised and dropped alternately, thus producing the beating motion for the carpet.

The carpet passes over the cross-bar b,- thence through between the two revolving brushes y gl; thence overthe cross-beam d., which sup ports the carpet, and thence through between the feeding-rollers j' f; thence downward to the floor, and, finally, back again to the'cross beam b, the ends of the carpet bein fastened together to make it endless.

The motion ofthe tecding-rollersfj", and also the motion ot' the revolving brushes, may be obtained directly from the cam-shaft I.

I claim as my inventionl. rlhe beaters, constructed each ot` two elastic bars or sprin gs, h h, and slats t' li, and operated by the cam-motion of the pins m m, substantially as and for the purpose specified.

2. Beaters constructed and operated substantially as specified, in combination with feed-rollers fj", situated as described, so as'to propel the carpet in an inclined upward direction, to cause the weight ot' the carpet below the said feed-rollers to keep the carpet straight and under tension while receiving the blows ot' the beaters, as set forth.
